MAGAZINE DEVELOPING-CAMERA.

Application filed February 3, 1911.

T 0 all whom it may concern:

Be it known that I, CHARLES F. SPERY, a citizen of the United States,and resident of Chicago, in Cook county, Illinois, have invented certainnew and useful Improvements in Magazine Developing-Cameras; and I dohereby declare that the following description of my said invention,taken in connection with the accompanying two sheets of drawings, formsa full, clear, and exact specification, which will enable others skilledin the art to which said invention appertains to make and use the same.

This invention has general reference to magazine developing cameras; andit consists, essentially, in the novel and peculiar combination of partsand details of construction, as hereinafter first fully set forth anddescribed, and then pointed out in the claims.

In the drawings already referred to, which serve to illustrate thisinvention more fully, Figure l is a side elevation of this improvedcamera. Fig. 2 is a plan of the same, one of the pivoted tank-containersbeing shown outwardly swung to afford access to the developing andfixing bath. Fig. 3 is an elevation of the camera looking toward therear of the'same. Fig. 4 is a similar view of the same looking towardthe front end thereof. Fig. 5 is a longitudinal sectional elevation online 2 e of Fig. 6, a portion only of the lens-tube being shown. Fig. 6is a sectional elevation on line or as of Fig. 5, looking in thedirection of the arrows shown. Fig. 7 is a sectional view of themagazine tube detached, the view being taken on line 3 y of Fig. 5. Fig.8 is a view of a portion of the magazine tube, illustrating the meansfor centering the photographic plates in said tube, the socket to whichthis tube is attached, being shown in section. Fig. 9 is a sectionalview of one of the photographic plates, and Fig. 10 is a face view ofthe same. Fig. 11 is a view, partly in section, of one of theplate-cartridges.

Like parts are designated by the same characters and symbols ofreference in all the figures.

The object of this invention is the production of an efficient,serviceable, and comparatively inexpensive magazine camera in which acomparatively large number of photographic plates are stored, whichplates are Specification of Letters Patent.

exposed and developed and fixed without the operator touching them withhis hand.

A, in the drawings designates the casing of this camera. It is a,preferably, cylindrical shell closed at its forward end by a head B, andat its rear end by a head C. In this forward head there is a largecentral opening which is internally screw threaded to receive a lenstube D, carrying at its for ward end a photographic lens E, of approveddesign, said lens tube D being of a length corresponding to the focallength of the lens E.

WVithin the casing A, and near the forward head B there is located apartition F, which partition is separated from the forward head byspacing-tubes 12, and secured, but removably fastened, to said forwardhead by screws 13. This partition comprises three separate plates 14,15, 16, respectively, of which the plate 14 faces the lens tube, and inwhich plate 14: there is a central opening 17, whose axial linecoincides with the axial line of the lens tube, and whose diameter isthat of the sight of the photographic plates used in the camera: Theplate 15 is crescent-shaped, as illustrated in Fig. 6, while the plate16 is, again, a circular disk the same as the plate 14, and it has acentral opening in alinement with the opening 17. At the rear face ofthis plate l6, and concentric with the central opening therein, there isaflixed a socket 18, in which there is secured a tube G, which tube isof an internal diameter somewhat larger than the external diameter ofthe protographic plates H, and of a length to pass through a centralopening in the rear head C and to project therefrom for some distance.At the outer end of this tube G, which tube constitutes the magazine forthis camera, there are oppositely-located, Lshaped cut-outs or slots 19,wherewith engages the inner ends of screws or pins 21, located in thewall of a cup-shaped member or cap I, to form therewith what is usuallytermed a bayonet oint, whereby said cap I is removably secured to theprojecting portion of said magazine tube G. In the forward end of thismagazine tube there are, preferably three, inwardly forced lugs orguides 20, which lugs are produced by slitting the tube G at the properplaces and forcing the portion of the tube between the adjacent slitsinwardly, whereby said inwardly forced portions 20 are made resilient,set-screws 22, tapped in the socket 18, being provided to impinge uponthe lugs 20 and thereby to afford means for adjustment of the same toaccommodate plates H of slightly varying external diameters.

In the magazine tube G there is located a spiral spring J, secured atone end in the bore of the cap I, and at its other end to the forwardend, and upon the outside of, a sleeve 23; a further spiral spring K, ofless diameter than the spring J being secured at one end to, and withinthe rear end of said sleeve 23, and carrying at its forward end a disk24, loosely fitting the bore of the tube G, and serving as a plunger, aswill hereinafter more fully appear.

In the space 25 between the forward plate 14 and the rear plate 16 ofthe partition F, formed by the crescent shaped plate 15, there islocated. a peculiarly-shaped rocking plate L, which plate is riveted orotherwise secured to the forward end of a shaft 26, located below thetube G, and having a bearing 28, in the rear head G, and a bearing 27,in the plate 16, said rocking shaft 26 projecting from the rear head Csufficiently to receive an arm or handle 29, by which the rocking shaft26, and with it the rocking plate L, are oscillated. The periphery ofthe rocking plate L forms the arc of a circle which has its center inthe center of the rocking shaft 26, and it has at both of itsextremities approximately semicircular cut-outs or notches 30, 31,located equi-distant from the center of the shaft 26, there being onsaid rocking plate L stops 32, 33, which engage an abutment 34, locatedin the space 25, so that when the plate L is moved in either directionuntil one or the other of its stops 32, 33, reaches said abutment, aphotographic plate in the proper notch will be correctly centered behindthe exposureopening in the partition F, to receive alightimpressionthereon when the lens shutter is opened to make an exposure.

Near the forward end of the casing A, and downwardly pending therefrom,and removably secured to said casing, there is a peculiarly-shapedcasting M, said casting comprising a fiat tube having lugs 35, 36,through which screws 37, are passed and a further lug 38, also receivinga screw 37, to secure the casting M to the casing A. This casting M isof approximately I-shape below its tubular part, that is to say it hasan upper horizontal plate 39, and a lower horizontal plate 40, saidplates being medially connected by a web 41. In the spaces at the sidesof the median web 41 there are located, preferably rectangular,receptacles N, O, which receptacles are each pivoted upon a verticallydisposed pivotal bolt 42, located at one corner of each receptacle, asindicated in Figs. 2, and 3, so that they may be rotated upon saidpivotal bolts 42. In each of these receptacles there is removably placeda tank, 43, 43 adapted to receive a preferably developing and fixingsolution.

From the space 25 in the partition F, and through the tubular portion ofthe casting M, lead downwardly, two angularly-disposed. passages 44, 44through the top-plate 39, to the tanks 43, 43*, as clearly shown in Fig.6. The upper surfaces of the receptacles N, O, as well as the lowersurfaces of the top plate 39 of the casting M, are well machined so asto prevent raysof light entering at the joints of these members; and toinsure perfect contact of the receptacles with the top-plate, 39, thereis located on each of the inner surfaces of the bottom plate 40, aspring 45, which spring forces the receptacles N, O, upwardly in amanner readily comprehended.

In operating, this camera is mounted upon the usual camera stand or atripod, not shown, to which it is secured by the tripod screw 46, shownin Fig. 5, and the magazine tube G filled with unexposed light-sensitiveplates H. These plates H are, preferably, packed in a shell 47, Fig.1.1, of an external diameter slightly smaller than the internal diameterof the magazine tube G, and slightly larger than the external diameterof the plates, there being a plug 48, in one end of said shell 47, and afurther, punctured, plug 49, at the other end thereof. This chargedshell or cartridge is pushed into the magazine tube G, plug-end 48foremost, and then the plates H pushed into the magazine tube bywithdrawing the shell 47, the cap I with the spiral springs J, K, andplunger 24, having been .firstremoved, and then the magazine tube closedby replacing the parts I, J, K, and 24. These spiral springs force thephotographic plates into contact with each other and the foremost onethereof against the inner surface of the rocking plate L the handle 29being in perpendicular position, and the exposure opening closed by saidrocking plate L. If now the handle 29 be turned to one side or the otherof its perpendicular position until either the stop 32 or the stop 33comes in contact with the abutment 34, one or the other of the cut-outs31, 32, (as the case may be) will permit the plates H to move forwardthe distance of the thickness of one plate and force the foremost plateagainst the inner surface of the front plate 14, concentric with theexposure opening 17 therein. The camera is now focused upon the objectto be photographed by looking through the rear sight 50, over the frontsight 51, the relative heights of which are so that the focal point infront of the lens is the center of such object, and the exposure anadein the usual manner. Now the rocking plate L is rotated by turning thehandle 29 in the proper direction to push the exposed plate into theproper passage 44, from which it drops into the developing and fixingsolution in the respective tank 43.

It will now be observed that a plate may be exposed and discharged intothe developer by moving the handle 29 from its normal, vertical,position either to the right or to the left thereof, that is to say,when the handle 29 is moved so as to cause the cutout 30 to receive aphotographic plate for exposure, and the handle is then returned to itsvertical position, the cut-out 30 will operate to push the exposed plateinto the passage 44, from which it will drop into the tank 43 Now thehandle may be again moved in the direction mentioned to bring thecut-out 30 in platereceiving posit-ion, or it may be moved in theopposite direction to cause the cut-out 31 to be moved inplate-receiving position when, after the exposure has been made and thehandle 29 returned to its normal vertical position, the plate in thecut-out 31 will pass through the passage 44 to the tank 43. In thismanner the photographic plates may all be received by either the cut-out30, or the cut-out 31, or alternately by one and then the other of thecut-outs, the latter being the case when exposures are made incomparatively rapid succession and a plate is occupying one of thedeveloping tanks while being developed and fixed.

When the handle 29 is in vertical position, the rocking plate L closesthe exposure opening, or rather acts as a shutter for the same, so thatshould the lens be accidentally opened, no exposure of a photographicplate can take place until the handle is moved from its normal positioneither to the right or to the left, as hereinbefore set forth. Thisfeature of my invention is an important one since it prevents doubleexposures and the exposure of a plate when not desired, while at thesame time a second exposure may be made while the first plate is in thedeveloping and fixing solution, thus making the operation of the cameraa practically continuous one.

I now desire to call attention to the fact that the interior or bore ofthe magazine tube G is larger in diameter than the exterior diameter ofthe plates H by at least the thickness of the cartridge shell 47 plusthe slight play which the shell has in the tube G, and the plates havein the shell 47 so that the plates when in the magazine tube will not bein exactly the center line of the exposure opening 17. To compensate forthis variation or eccentricity, I may locate the magazine tube Gslightly above the central position to bring the plates into the properposition, but I prefer the centering device shown in Figs. 7 and 8, forthe reason that by this device the plates are positively centered behindthe exposure opening even though there be a variation in the diameter ofthe plates which will be taken care of by the resilient lugs 20, while agreater variation in the diameter of the plates will be compensated forby making proper adjustment with the screws 22. I also desire to callspecial attention to the arrangement of the springs in the magazinetube, whereby the spring K telescopes in the sleeve 23, while the springF gathers upon the outer periphery of said sleeve when entirelycompressed. This construction affords me the necessary length of thespring without unnecessarily lengthening the apparatus or the magazinetube, and at the same time materially reduces the cost of the apparatus.

In order that this camera may have the prevailing appearance of aphotographic camera, I cover the casing A with black morocco leather, asindicated by the heavy lines 52 in Figs. 5 and 6. This leather coveringof the casing also serves as a packing between the metallic shell of thecasing and the lugs 35, 36, and 38 on the casting M, to prevent lightfrom entering the passages 44, 44 and the space 25 between the plates 14and 16 of the partition F.

Most of the parts entering into the construction of this camera, I shallproduce from sheet and cast aluminum so that the apparatus will becomparatively light in weight and easily carried about by a person.

It is obvious that when the photographic plates have been pushed intothe magazine tiibe, the plug 48 is foremost therein and has to beremoved before the photographic plates can be exposed. This is done inprecisely the same manner as described with reference to exposing anddischarging a photographic plate, that is to say by moving the handle 29first to one side of its normal position and then moving it back to itsnormal position.

Having thus fully described this invention, I claim as new, and desireto secure to me by Letters Patent of the United States- 1. In aphotographic magazine camera, the combination, of a casing, a magazinetube in said casing constructed to receive photographic plates, a platein said casing having an exposure opening, means in said magazine tubefor moving said plates toward the latter plate concentric with theexposure opening therein, said means including telescoping springs, andmeans constructed to discharge said photographic plates from saidcasing.
